What is the unit of electric charge?

The unit of electric charge is the coulomb, represented by the symbol "C." A coulomb is defined as the amount of charge that passes through a conductor when a steady current of one ampere flows for one second. This unit is foundational in electricity and helps in quantifying how much charge is being stored or moved in electrical systems.

Understanding this concept is key because electric charge is a fundamental property of matter that causes it to experience electric forces. The other units listed, such as volt, watt, and ohm, relate to different aspects of electrical systems. Volts measure electric potential or voltage, watts are a measure of electrical power, and ohms measure electrical resistance. Each of these plays a critical role in the study of electricity, but they do not represent electric charge itself.
